Print dispatch truth (counterpart/1)

An error from print_3mf, upload_gcode or process_and_print_stl carries structuredContent.printOutcome: not-sent means no print command was handed to a transport (including fresh-report timeouts, preparation failures and upload failures); unknown means a command may have reached the printer; rejected means the printer refused the command. A file upload alone is not a print command. Clients use this field, never error wording or firmware codes, to distinguish “Not started” from a print that needs checking. Missing or unrecognized values cannot prove nothing was sent. Other structured error fields remain compatible.
